Abstract:
Methods and apparatus related to control channels in a wireless communications system are described. Different white space bands may be available at different locations. A wireless terminal monitors control information from multiple potentially available communications channels. Control time slots corresponding to some different channels are intentionally time offset from one another. Some embodiments implement predetermined control slot timing synchronized with respect to an external timing source. In other embodiments, a wireless terminal selects a control time slot on a new channel as a function of control slot timing on channels already in use. A wireless terminal selects one of a plurality of communications channels for use in communicating information and determines a position of a control time slot to be used on the selected communications channels. The wireless terminal uses the control time slot on the selected communications channel to transmit and receive control information.
